Methodology

Each point counts distinct signals detected that calendar week (Monday–Sunday, UTC) from primary public sources — job-board diffs, state WARN feeds, official business registries, and DNS records — deduplicated per company. The series reflects what we observed as it happened; historical values are never restated. Cite this page with a link to ChangeSignal.
